@RCHER FOR MENUET v1.0 July 14, 2005
Written in pure assembler by Ivushkin Andrey aka Willow
Deflate unpacker
Vivat assembler et MENUETOS!
I tender thanks to everyone who spends his time in feasible effortsfor that
little OS evolution. Now in my own rating the Mario79's distro named Kolibri4
takes 1th place. It is always pleasant to use modern software. Go on!
@RCHER is intended to view & unpack data compressed by Deflate method
(including both static and dynamic Huffman). This method (although it isn't the
best already) is used by such file formats as ZIP (modern versions: PKZIP for
MS-DOS can create archives using other, less effective compression methods,
which @RCHER doesn't support), GZIP, JAR, OpenOffice files, SFX ZIP executables
and some others. I couldn't prevent myself to include support of PNG images
(they use the similar compression) and TAR and TAR+GZIP archives.
When the program is started, a little button carrying a @ symbol appears in the
left top corner of screen. Clicking this button opens a SYSXTREE dialog to
select a file being unpacked. Doubleclick closes the application. @RCHER
outputs its information messages to Debug Board. If an archive contains more
than one file, the 1st is by default unpacked into /HD/1/OUT.TXT (you may
change the DUMPFILE constant in @RCHER.ASM) and is opened through TINYPAD
or - if it's a PNG image - in the built-in viewer.
These are unpacking flags that may exist in a commandline before an archive
filename:
s - do not close the program after unpacking;
n - decompress the K-th archive file, where K is the following dword in
commandline;
N - decompress the K-th archive file, where K is ASCII number from the
following 6 bytes of commandline;
R - "raw" Deflate data, without descriptors and headers;
q - begin file parsing from offset of K, where K is following dword in
commandline;
Q - begin file parsing from offset of K, where K is ASCII number from the
following 6 bytes of commandline.
Commandline example:
cmd_string:
db 'sN000037q'
dd 1465
db '/hd/1/png.zip',0
It means to open the 34th (counting from 0) file of archive /hd/1/png.zip
and do not terminate. Archive will be parsed starting at offset 1465.
To-Do list:
1. Support for interlaced PNG, alpha-channels, gamma-correction, background,
Significant bits and a lot of cool parts of that format.
2. Output of archive content through IPC or into a built-in window like SYSTREE
(as we are going to decide with the respected colleagues).
3. Searching of archive files by name and wildcards!
4. Unpacking into a file specified.
5. Means on saving memory space (now @RCHER gorges 8 Mb!): moving RAM areas,
blocked file output. To do the last thing it is necessary to test carefully
the reliability of harddisk I/O, directory creation and file deletion. These
kernel capabilities aren't still documented.
6. Archive contents integration into SYSXTREE & MFAR filemanagers. We have to
unify the calling format (like a structure in the sysfunc 58).
7. Add comments to source.
8. Correct bugs to be found
